Which of the following is NOT a component of a basic skincare routine?

Tanning is not a component of a basic skincare routine, making it the correct answer. A basic skincare routine typically focuses on maintaining and enhancing the skin's health and appearance through practices that cleanse, exfoliate, and moisturize.

Cleansing is essential for removing dirt, oil, and impurities from the skin, thus preparing it for the application of other skincare products. Exfoliating helps to remove dead skin cells, promoting a smoother and more radiant complexion. Moisturizing is crucial for hydrating the skin and preventing dryness.

In contrast, tanning involves changing the skin's color—either through sun exposure or artificial means—but does not contribute to the fundamental health or maintenance of the skin itself. Instead, tanning can lead to various skin issues, including premature aging and an increased risk of skin cancer, which are counterproductive to the goals of a skincare routine.
